Compare a volkswagon and a mack truck,
both moving at 60 mph. The truck takes
longer to stop, and requires more energy
to stop, than the little VW.
I thought you were wrong on this one, Lumpy. This is a common
freshman physics problem, and the truck and car should stop in the
same distance because the truck tires have more friction with the road
due to its greater weight...However, empirical
data say you're right...
The truck also has 18 wheels, all larger than the
VW, and bigger brake surfaces. It needs more
(and has available more) energy to cause
it to stop than the VW.
There's probably even wind resistance
to factor in.
Loaded trucks take longer to stop
than empty trucks if they are traveling
at the same speed and have the same amount
of braking force applied to them.
But if we equalize all the variables (put the
VW brakes on the truck) the "body in motion
would tend to stay in motion" longer for
the bigger rock.
With guitar strings, we "equalize the variables"
by tuning the two strings (light and heavy)
to the same pitch. We have to increase the
tension on the larger string to make the
pitches equal (bigger engine = increased tension).
Reduce some of the variables by thinking
in terms of waves of energy instead of
cars on a road. You can stand in a
kid's wading pool and your body can
block/alter the ripples (tiny waves)
on the surface of the water.
Stand in the path of a Tsunami tidal wave
and your body can't do much at all to
alter the (much heavier) waves.
Or sound waves. You can block small sound
waves compkletely by putting your hand or a pillow
over the speaker of a small radio.
Putting that same hand or pillow over
the speakers at a rock concert would have
little/less effect on blocking the sound.
You'd need a much bigger hand or pillow
to stop the much bigger waves.
